And why do you think this isn't intentional? Spending money on people solving company's screwups costs a lot of money. For the company the size of Google or Facebook one client (or hundred) like this are peanuts, drop in the bucket. The cost of losing them is minimal over the costs of paying a support person to deal with problems.
Big client won't get banned - and if they do, they have also a non-public phone number to an account manager to make things right again too.
Sadly this is a common trend - e.g. with ISPs it is almost impossible to find a contact to an actual person, only some online chats or automated hotline that will waste your time with canned responses not solving your problem.
